Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bandwidth is increased to support advanced RATs (5G, mmWave, carrier aggregation), then data transmission rate and service capability are improved, but power consumption increases and battery life deteriorates
Solution Approach 1:
The patent implements dynamic bandwidth adjustment by monitoring application states and automatically modifying RAT configurations. The system transitions between different bandwidth modes (e.g., carrier aggregation on/off, mmWave sub6GHz switching) based on real-time application requirements, enabling the device to adapt power consumption to actual usage needs rather than maintaining fixed high-bandwidth configurations
Solution Approach 2:
The system changes key communication parameters including bandwidth part (BWP) configurations, subcarrier spacing, and RAT selection based on application states. By modifying these parameters dynamically, the system optimizes the balance between data transmission capability and power consumption for different application scenarios
2Use of energy by moving object
If manual user intervention is required for power saving modes and application management, then power consumption can be optimized, but ease of operation deteriorates and user convenience is reduced
Solution Approach 1:
The patent implements a self-service power optimization system that automatically monitors application states, determines optimal bandwidth configurations, and executes RAT adjustments without user intervention. The system independently manages power-saving modes, application prioritization, and communication technology selection, freeing users from manual configuration while achieving power optimization
Solution Approach 2:
The system continuously monitors application states and uses this feedback to automatically adjust bandwidth and RAT configurations. By establishing a closed-loop control mechanism that responds to application behavior, the system achieves adaptive power optimization without requiring users to understand or configure technical parameters
3Productivity
If system bandwidth is distributed across multiple RATs (5G, 4G, Wi-Fi), then application performance and service capability are improved, but device complexity increases
Solution Approach 1:
The patent segments system bandwidth across multiple RATs (5G NR, 4G LTE, Wi-Fi) and independently manages each segment based on application requirements. By dividing the communication resources into separate manageable segments rather than treating them as a monolithic system, the patent simplifies the control of complex multi-RAT environments while maintaining overall performance optimization
